SPECIICATION forming part of Letters Patent No. 295,300, dated March 18, 1884.

Application tiled December 2li, 1883. (No model.)

fo' all when?. t may concern.:

Be it known that I, RxLrH R. SPEARS, a citizen of the United States, residing at W'heeb ing, in the county ol' Ohio and State otl Test Virginia, have invented a new and useful Improvement in Lifting-Jadis, ofwhioh the following is a specification, reference being had to the accompanying d rawings.

My invention relates to lil'ting-jaelzs; and it has for its object to provide a device o' this character' which shall be cheap, simple, and durable in its eoustruotion and thoroughly eden-.tive in its operation. Vith these ends in view the invention eonsistsin theimproved construction and combinations of parts, hereinafter fully described, and pointed out in the Claims.

In the drawings, Figure l is a perspective view of a liftingjnok constructed in aeeordance with my invention. Fig. 2 is a vertical section oi' the same.

A represents two vertical standards or uprights connected at their upper ends by a block or erosslbar, o, and at their lower ends by a supporting-beam, u. The standards or nprights A are provided on their sides with any desired number of perforations, b, to receive a bolt or rod, b', which passes through a perforation, c, in the lever C. thereby pivoting said lever between the parallel uprights A. This lever G is provided at its upper end with a braeket or casting, d, having the angu` lar portion d', which is slightly out away to forrn a seat for the axle of a vehicle when it is desired to raise the same, and is also provided with the arms di, which embrace the end of the lever C, thus forming a secure oonneetion. Near the lower end ot' the lever C is pivoted, by means of an eyebolt or staple, a rack-bar, which is provided at its end with a perforation to receive said staple or eyebolt, or, il' desired, the saine may be secured bya hinge to the lever G. This rack-bar D is formed with the teeth e, whioh engage with a plate or strip of metal, F, secured to the sides ofthe standards A.

From the foregoing description it will be apparent, that when it is desired, the lever C may be vertically adjusted by removing the pin or bolt b to one oi' the lower or higher u engage therewith, and upon the depression of the lever C the wheel of the carriage will be raised a snfiieient distance from the ground to allow ot' its removal, the rack bar D engaging with the plate F, thus preventing the lowering ol" the axle, exeept in the event of the raek-bar being removed, which is the oase when it is desired to lower the axle and wheel.

Thus it will be seen that while my improvement is simple and cheap in its construction it is effective in its operation.

Having iull y described Iny invention, what I elai in as new, and desire to secure by Letters Patent, is-

l. In a liftingfjack. the. combination, with two nprights, ot' a lever pivoted between said uprights, said lever being provided with an angular braelret at one end, its other end heing provided with a pivoted rack-bar to engage with a plate upon the said standards, substantially as set forth.

2. In a lifting-jack, the combination, with two uprights, ot' a lever pivoted between said uprights, said lever being provided with an angular bracket, d. having the extensions or arms d2, to engage the ends of the lever at one end, and provided near its lower end with a pivoted rack-bar to engage a strip or plate secured to the sides of the standards or uprights, substantially as set forth.

In testimony that I elai n1 the foregoing as my own I have hereto affixed my signature in presence ol' two witnesses.

RALPH REED SPEARS.
